A look at a memorable moment in Seahawks history that occurred on March 31.

2005: Matt Hasselbeck is signed to a multi-year contract and Shaun Alexander is given the franchise tag. Both would be instrumental in the Seahawks’ run to the Super Bowl that season. Alexander scored a then-league record 28 touchdowns and led the NFL in rushing while being voted league MVP, while Hasselbeck passed for 3,459 yards and 24 touchdowns in compiling a career-best 98.2 passer rating.

1989: Tom Flores is named president and general manager to replace Mike McCormack. Flores became head coach in 1992, replacing Chuck Knox.

2002: Three-time Pro Bowl defensive end Michael Sinclair is released. Sinclair leaves after producing 73½ career sacks, including a league-leading 16½ in 1998, to rank second in franchise history to Jacob Green (116).
